BUTTON-SETTING MACHINE.

Application filed October 14, 1916, Serial No. 125

To all whom it may concern:

Be it known that I, FRANK C. SNYDER, a citizen of the United States, residing at Scottdale, in the county of l/Vestmoreland and State of Pennsylvania, have invented certain new and useful Improvements in ButtonSetting Machines, of which the following is a specification.

This invention relates to button setting machines, and resides in certain details of construction of the button feed and staple forming and setting mechanism conducive to economy in manufacture of the machine.-

One feature of the invention is the use of a two part swinging hammer with a novel connecting mechanism and retracting anvil. This construction simplifies the guides and actuating mechanism and provides astrong durable setting head which will thread the buttons with the staple wire, cut and form the staples from a continuous length of wire and set the staples. The principal parts are all mounted on a single pivot and guide each other, while the number of small parts, springs, &c., is reduced to a minimum.

Other features of invention relate to details of construction and will be apparent from a description of the invention as embodied in the button setter illustrated in the accompanying drawings. In the drawings Figure 1 is a side elevation of the complete machine, parts of the casing and frame being broken away to show the operating parts;

Fig. 2 is a front elevation of the upper part of the machine;

Fig. 3 is a section through the wire guide showing the wire feeding arm;

Fig. 4 is a side elevation of the same;

Fig. 12 is a side view partly in section of the setting head parts in the position of Fig. 9.

The machine is carried on a hollow pedestal 15 which commonly would be of cast Specification of Letters Patent.

iron, and this pedestal incloses an actuating pull rod 16connected to an actuating treadle 17 held normally in its upper position a coil spring 18.

On the top of the pedestal 15 is the main housing 19 of the setting head. This hous ing is hollow and open at its front face to expose the rivet forming and setting hammers 20 and 21 which are pivoted on a journal pin 22 common to the two, the setting hammer 21 beinghoused in a slot in the forming hammer 20. These two hammers 20 and 21 coact with a fixed anvil 23 having an inserted clenchingface 24 formed as shown clearly in Figs. 9 to 11, so as to clench the end of the staples toward each other in the usual manner.

The hammer 21 carries adepending plate 2 or lug 25 which is connected at '26 by a pivot to the actuating pull rod 16. At the beginning of downward motion thehammer 20 is latched to the hammer 21'by a latch 27 which is pivoted at 28 to the lug 25 and is held by a spring 29 behind a shoulder30 on the hammer 20. The two hammers thus move together until the hammer 20 contacts with the work on the anvil 23. At this moment the tail or cam 31on latch 27 strikes stop pin 32 and is tripped, thus releasing hammer 21 for further movement.

The lug 25 is formed with a cam slot 33 through which passes .a pin34 on the end of a sliding forming anvil 35. This is mounted for longitudinal movement in a guide 36, and is retracted by the cam 33 shortly after the hammer 20 has passed it to out and form into a staple a length of wire 37 fed through guide 38 in housing 19.

The wire is drawn from a spool 39, rotatably mounted at the back ofthe machine, by a'serrated clutching face 40 on a feed arm 41. The arm- 41 is pivoted at 42 and its; clutching face 40engages the wire whilethe latter is held by a guide tube 43 which leads to the guide 38. The guide tube 43 is cut away at 44 to permit the clutching face 40 to engage the wire andthe necessary pressure.

is secured by the resilience of the parts.

The arm 41 is fast to a secondarm' 45 and shear off the length of wire projecting over anvil to form a staple,

the hammers 20 and 21. When the treadle is released and has moved nearly to the limit of its upward motion, a stop 19 on rod 16 trips latch 18 and releases arm 45. The feed arm then snaps forward under the action of spring 46 feeding the wire 37 through tube 43 and guide 38 across the open front of housing 19.

The wire passes just over the top of the forming anvil 35 and through the shank or loop 50 of a button 51, held thereon by feed finger 52. The anvil 35 has a slot 53 to assist in retaining the button shank and the setting hammer 21 has a similar slot 5 1. The forward feed of the wire is arrested by the collision of the end of the wire with the housing 19 at the opposite side of the slot in which the hammers 20 and 21 swing, the front of the housing 19 having an opening or slot for the hammers as already stated.

The forming hammer 20 has slots 55 which engage and retain the wire 37 as the hammer descends, the hammer servingbto yond guide 38 as its lower face passes this guide. At the moment of shearing this short length of wire is held over forming anvil 35 by the slots 55. On the continued downward movement of hammer 20 the ends of the length of wire are wiped down and are then held by the forming guide slots 56 in hammer 20 (see Fig. 10).

The button magazine consists of a box 57 removably mounted on top of housing 19 by means of headed lu s 58 which enter key hole slots 59 in the bottom of box 57. Its approximately sector form is clearly shown in the drawings. At its lower corner it has a door 60 held closed against the weight of the contained buttons by a spring hinge 61. The door 60 projects edge of box 57 and is struck open by the transfer cup 62 to discharge buttons from the box 57 into the cup, to fill the latter. The cup 62 is mounted on an arm 63 which is pivoted at 64:, about which point the arc of the curved side of box 57 is struck, and

tons from has a pin and slot connection 65 with hammer 20. This connection is such that when the hammer 20 is swung down cup 62 swings down and receives a charge of butthe magazine. When hammer 2O swings up, the cup 62 also swings up, travel- "ing along the curved side of box 57 and finally discharges its buttons into the open top' of the box.

The buttons so discharged fall over a nar row guide plate 66 having a longitudinal slot 67 Certain of the buttons will be caught by the guide plate with their shanks in the slot and the remainder will fall down into the box or magazine 57. The buttons so caught will slide down the guide plate until arrested beyond the curved by the impositive spring finger stops 68 which engage and hold the foremost button of the series in the slot 67.

Successive foremost buttons of the series in the slot are caught and fed to the anvil 35, one at each actuation of the machine, by the feed finger 52. This has a recessed end to engage the button head and is pivoted to an arm 69. A spring 70 urges the feed finger 52 against the button heads. The arm 69 is pivoted at 71 to housing 19 and has a pin and slot connection 72 with hammer 20 so arranged that finger 52 moves upward to get a fresh button as hammers 20 and 21 move down. On the reverse movement the finger 52 draws a fresh button through stops 68 and brings it to position just as anvil 35 is projected to its outward position to support the button, and just as stop 49 trips latch 48 to feed the wire. The wire is thus fed through the shank or loop of the button just as it comes into position. A slotted plate guide 73 forms a continuation of guide 66 below stops 68 and is carried on housing 19.

Starting with the parts in normal position the operation is as follows Both hammers are up, a button is on anvil 35 and is held by finger 52 and the wire has threaded through its shank. The article to which the button is to be stapled is placed on anvil 23. The treadle 17 is suddenly pushed downward its full stroke and then allowed to return.

On the down stroke cup 62 swings down, opens door '60 and receives a charge of buttons. At the same time finger 52 is moved up and engages the foremost button in guide 66. Hammers 20 and 21 start down together, hammer 20 shearing off the staple length of wire threaded through button shank 50 and then forming it into a staple by bending it over anvil 35. As the face of hammer 21 reaches anvil 35 this is retracted and the two hammers continue to move together until hammer 2O contactswith the work on the anvil 23. At this point latch 27 is tripped and hammer 21 descends independently of hammer 20, forces the staple through the sheet of material to which the button is to be attached and clenches it against the clenching surface 24.

On the up stroke the hammer 21 rises independently until it picks up hammer 20 when both hammers move together to their upper positions. As hammer 2O rises cup 62 swings up and discharges its buttons and arm 69 swings down and places a button on anvil 35 just after this is projected to its forward position. At the final limit of motion latch 48 is tripped and the wire feed is actuated.

To change the style of button the magazine is slid diagonally upward and forward to release it when it is lifted off and another substituted. A simple actuation of the dispose of the button in position on anvil Various modifications obviously arepossi ble, and the actuating mechanism and'wire feed in particular are shown for illustrative purposes alone and their'torm is immaterial.
